TOBACCO-FEEDING MECHANISM FOR ClGARETTE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 424,443, dated March 25, 1890. Application filed June 27, 1889. Serial No. 315,800. (No model.)

cigarette-machines, which improvements are full y described and illustrated in the followin g specification and the accon'ipauyin g drawlugs, and the novel features thereof specified inthc claims annexed to the said specification.

in the accompanying drawings, representing my improved tobacco-feeding mechanism for cigarette-niaehines, Figure 1 is a longitudinal section. Fig. 2 is a side elevation.

In the accompanying drawings, A represcnts an endless eonveving-belt, which travels i d by the motion of receptacle I is provided with around therollers l5, 0, and Din the direction represented by the arrows. As represented, a portion of the belt is arranged in the horizontal or nearly horizontal position, and the other part of the belt is inclined upward, being placed opposite the belt l which travels around the pulleys F and G.

In the. operation of the machine the tobacco is placed by an operative on the horizontal portion of the beltA, being spread over the surface in as uniform a layer as it may be conveniently, and the tobacco is carthe belt into the throat between the rollers (J and F, and it-is then carried upward between the belts to their upper ends, where it is subjected to the action of the revolving brush ll, by which itis dis entangled and fed downward into the hopper l, at the lower end of which it is discharged by the revolving rollers J J onto the second revoking brush K, whence it-is delivered to the ii llenlorming mechanism. The hopper or vertical walls,

and it serves to regulate the quantity of to baceo fed to the iiller-forn1ing devices, as any ore ss of tobacco fed onto the bolt A will ac .late in the hop p :r, being grad ually withwe therefrom and delivered to the lilleror by the roils J J, which are made adb e relatively to each other, so as to increase or decrease the width of the throat between them. iVhen there is no tobacco between the belts, the belt i A will travel up against the roller F. The belts are made of any suitable width-say fiveto eight inchesadapted to carry the requisite amount of tobacco. I make the roller 13 movable lengthwise of the belt, so as to maintain the requisite amount of tension on it. Any suitable device may be employed for this purposesuch, for instance, as the springs L, Fig. 2, bearing at one end against a sliding box in which the shaft of the roll revolves and at the other end provided with an adjusting-screw O. ported by a suitable f ramc U 011 each side of the apparatus, which frame may be provided with the legs V, by which it is sustained at a suitable height. The shaft of the roll F is carried by arms (Z, Fig. 2, attached to the frame U. The side pieces constituting the The shafts of the various rollsare supframe are connected together by suitable cross-bars extending across between the belts. The rolls G- and D'are made adjustable relatively to each other and the brush H by providin g their shafts a a with boxes, which are secured in place in openingsin the frame by the adj usting-screws c c. The shafts b b of the rolls J J are made adjustable in a similar manner. The brush II revolves within a suitable casing Q, Fig. ,2. The brush K revolves within a suitable hopper P, from which the tobacco is delivered to any suitable fillerforming mechanism-such, for instance, as the revolving compressiiig-rings described in my patent, No. $06,613, dated July 9, 1889. The rolls D G and J J are caused to revolve at the same speed in any convenient manner,

Thus the shafts of the rolls 1) and J may be provided with the worm-gears RR; operated by the shaft S by means of the worms T .T. Any other suitable arrangement may, however, be adopted. The shafts a a and b b are provided with spur-gears of equal size, so that the rolls supported by the shafts travel at the same speed. The brushes II and K are driven at a higher speed than the rolls by means of belts running over pulleys on the shafts of the brushes, or in any other suitablc or preferred manner. Uniformity of the feeding operation is secured by the hopper I, in which any excess of tobacco placed en. til;-

Ice

belt A accumulates, being; gradually withdrawn by the rolls J J. The side or sides of the hopper I are made of glass, so that the operative can see whether or not the proper amount of tobacco is being supplied to the belt A. The brushes are made of stiff bristl es; but the ordinary wire picker may be employed, if preferred. In case the eonveyer or feed belt be run horizontally throughout its entire length the belt E maybe dispensed with; but its use enables me to allow the operative to stand on the floor.

I clain1- i 1. The combination, with. the feed-belt A, running around the roll I) at its delivery end, of the revolving brush 1T, regulatinghopper-I, the revolving discharge-rolls J ,J'- at the lower end of the ll0]l1l()l,lll0 revoking brush K, located below the discharge-mils, and a suitable discharge-spout, suliistnntially as described.

*2. The coinbinz'ttion, with the feed-belts A and E, running around the rolls D and G at their delivery ends, of the. revolving brush H, regulating-hopper I, the revelvirg discharge-rolls J J at the lower end of the hopper, the revolving brush ll, located below the disehargerolls, and a suitable dischargespout, substantially as described.
